Abstract

A liquid crystal display includes a gate line formed on a lower substrate, a storage line formed on the lower substrate, and a data line formed on the lower substrate crossing and insulated from the gate line and the storage line. The liquid crystal display also includes a pixel electrode formed on the lower substrate crossing and insulated from the storage line. The pixel electrode has a first aperture pattern. The liquid crystal display further includes a common electrode formed on an upper substrate and having a second aperture pattern, and a storage electrode connected to the storage line. The storage electrode overlaps the second aperture pattern. The storage line, first aperture pattern, and second aperture pattern each includes a straight portion slanting to the gate line. A long axis of a liquid crystal molecule is arranged perpendicular to a substrate when an electric field is not applied.

Claims (19)

1. A liquid crystal display, comprising:

a gate line formed on a lower substrate;

a storage line formed on the lower substrate;

a data line formed on the lower substrate crossing and insulated from the gate line and the storage line;

a pixel electrode formed on the lower substrate crossing and insulated from the storage line, the pixel electrode having a first aperture pattern;

a common electrode formed on an upper substrate and having a second aperture pattern; and

a storage electrode connected to the storage line, the storage electrode overlapping the second aperture pattern;

wherein the storage line, first aperture pattern, and second aperture pattern each comprises a straight portion slanting to the gate line,

wherein a long axis of a liquid crystal molecule is arranged perpendicular to a substrate when an electric field is not applied, and

wherein the first aperture pattern comprises:

a first and second aperture extending through the pixel electrode obliquely from a left boundary to approximately a fight boundary of the pixel electrode, the first and second apertures formed symmetrically with respect to a center of the pixel electrode; and

a third aperture extending into the pixel electrode horizontally a predetermined distance from the right boundary.

2. The liquid crystal display of claim 1 , wherein the storage electrode comprises a straight portion slanting to the gate line.

3. The liquid crystal display of claim 2 , wherein the storage electrode slants to the gate line.

4. The liquid crystal display of claim 1 , wherein the first aperture pattern and the second aperture pattern are arranged alternately.

5. The liquid crystal display of claim 4 , wherein the second aperture pattern comprises:

a first and second aperture extending obliquely and symmetrically to each other; and

a third aperture angled at a mid point and formed on the common electrode;

wherein the third aperture of the common electrode is equidistant from the first and second apertures of the common electrode.
